Hi Ross,
If an RTSP request belonging to an established session is sent over a new TCP connection, the server seems to respond with a "405 Method Not Allowed". According to the RFC, RTSP requests can be transmitted in several different ways including one connection per request/response transaction? This is especially a problem on android devices that experience connection issues. It seems network issues *sometimes* cause subsequent RTSP requests to be sent over a new connection resulting in the 405 response. We've observed this using VLC on android (which uses live555) and replicated it with a python script using the *latest* version of the live555 RTSP server.
